BICYCLE DRIVETRAINS
MODEL N170S
NuVinci CVP
The NuVinci Continuously Variable Planetary
(CVP) is a revolution in drivetrain technology.
A new way of transmitting mechanical
power based on spheres instead of gears.
It’s a new class of highly adaptable
and scalable continuously variable
transmission (CVT), the first commercially
available for the bicycle industry.
And a genuine replacement for
internally geared hubs and derailleurs
that is ideally suited for comfort,
cruiser and commuter bicycles.
NuVinci CVP-equipped bicycles offer
riders the quietest, smoothest ride ever.
They completely eliminate the jerkiness
of missed shifts, dropped gears and
gear lash. Adjusting the ratio to adapt
to the terrain and the individual’s fitness
and riding style, is as effortless as
adjusting the volume on a radio. No
noise or hesitations. Riders intimidated
by conventional shifting need never suffer
a missed gear or dropped chain again.
The NuVinci CVP is the culmination
of a century’s worth of continuously
variable transmission advances.
Variable planetary configuration provides the
rider a smooth speed ratio change experience
in a compact, very durable package. Easiest
shifting ever!
Simple twist controller enables easy, continuous
ratio adjustments while pedaling, coasting or at a
stop. Easy to read display makes it simple for the
rider to find the perfect cadence “sweet-spot”.
The NuVinci CVP advances the state of the art in
elastohydrodynamic lubrication and traction CVT
technology, and combines it all into a package
practical for a bicycle for the first time.
2007 Batavus Adagio-NuVinci
Bike of the Year
It benefits from strong automotive "DNA"
in CVT technology providing world class
reliability, durability and OE quality.
Represents game-changing breakthrough
technical achievements that will attract more
riders and grow the bicycle industry, including
comfort/cruiser riders, technophiles, performance
lifestyle and luxury riders of all ages.

Driving the NuVinci TM
Revolution
The NuVinci CVP is a CVT that functions like a
planetary gear set as well. The NuVinci CVP
typically has a central idler, a set of balls
distributed about the idler, a rotatable input
disc on one side of the idler and the balls and a
rotatable output disc positioned on the other side
of the idler and the balls. Tilting the axes of the
balls varies their respective contact diameters
with the input and output discs, varying the
transmission ratio.
The result is smooth, seamless and continuous
transition to any ratio within its range, maximizing
overall powertrain efficiency.
Riders can adjust the ratios continuously as the
terrain changes. Whether they are in motion or
standing still. This allows for total control unlike
any other bike.
